Remember the difference between "Allowable Voltage Range (2.500-3.650)" compared to "Working Voltage Range (3.000-3.400) which can be safely extended to (2.800-3.400)" volts per cell. A "Surface" charge where Amps Taken remain high will not provide full saturation to that Voltage Level. If you charge to 14.0V and the amps drop to <5A then the cells are "saturated" to that voltage and you get everything back out. Without that Full saturation, its like driving on a 1/2 full tires while hoping for great mileage (never gonna happen).

So we were at the house 4 days with the Humsienk powering the camera WiFi starting at only 13.2-3 charge. Watched the cabin all weekend until Monday, no connection. Got back to the cabin, Hummer at 2 volts. Jumpered it to the bank, shot back up. I guess I can do that on a regular basis?
